#8 Add switch to disable server side file access

[Doron]

Current a user can save/load report files from the
server. Add option to disable either. Also add option
to provide a single list of predefined reports to allow
users to view already created reports but not access to
file system.

Required for multi-user demo. True security system to
be integrated for Beta.

been limited to 1 directory containing reports.
